I have some data files that were created without newlines that need to be fixed.
The files contain a bunch of records with an xml file name at the end.
They look like...

somedata file.xmlsomedata file.xmlsomedatafile.xml ....

what I want them to be is ...

somedata file.xml
somedata file.xml
somedata file.xml
...

So , i thought I could use a piecewize regex like so...

 pos $data = 0;
 my $len = length $data;
 while (pos $data < $len) {
     if ( my ($line) = $data =~ m{ \G ( .+  \. xml ) }gcxms ) {
         print "$line\n";
     }
 }

The problem is I cannot figure out how to make the regex non-greedy. My capturing portion matches the full string, all the way to the last xml file. How to I change the regex to be non-greedy and match up to the first xml file?
